Unlocking the Human Genome(基因组)
1 A project to unlock secrets一what scientist could resist that challenge?This is what many
scientists are doing as they work on the Human Genome Project.The aim of the project is
to decode(破译)all of the some 100,000 genes in the human body. Scientists are using
DNA fingerprinting techniques to do the decoding.
2 DNA is the substance found in the chromosomes(染色体)of a cell. A chromosome is a
chain of genes.Each gene carries a piece of genetic information.At any one moment in a
cell, thousands of genes are turned on and off to produce proteins(蛋白质).The challenge
for scientists is to find out what role each gene plays in protein production.At some point
this decoding will be complete.Then scientists will have a map of an ideal genome,or a
picture of the total genetic nature of a human being.The ideal genome is called a
consensus(交感)genome. Everything works well in a consensus genome.
3 But no one in the world has a consensus genome.Everyone's genome is different from
the ideal. These differences are referred to as genetic mutations(突变).Genetic
mutations in a person's genome mean that the person has a greater than average chance of
suffering from health problems.Some problems are not life-threatening.These would
include things like colorblindness,or mild headaches.Other problems are serious,such as
heart disease,or cancer.
4 It will take years to identify the role of each of the 100,000 genes.The short-term goal of
the project is to find the physical and mental health problems a person is likely to encounter
during his or her lifetime.The long-term goal is to have each person live a longer,healthier
life.
